建造修改器

The Build Modifier causes the faces of the mesh object to appear or disappear one after the other over time.

By default, faces appear in the order in which they are stored in memory (by default, the order of creation). The face/vertex order can be altered in Edit Mode by selecting Sort Mesh Elements from the operator search menu Spacebar.

Note

使用 Blender 渲染器时,如果网格的材质是光晕而不是标准材质的话,那么逐渐显现的是网格的顶点,而不是面。

选项

开始
创建过程的起始帧
长度
创建物体所用的帧数。
随机化
创建物体的面时,顺序随机化。
种子
The random seed. Changing this value gives a different "random" order when "Randomize" is checked -- this order is always the same for a given seed/object set.
Reversed
The modifier will operate in reverse, essentially allowing it to be used as a "deconstruction" effect. This is useful for making a set of dupli-objects gradually disappear.

Example

The Build Modifier is often useful when needing a way to get a large number of items to progressively appear, without resorting to animating the visibility of each one by one. Examples of this include a mesh containing vertices only, which is used as a duplivert emitter, and has the build modifier on it. Such a setup is a workaround/technique for being able to art-direct some semi-random layout of a collection of objects (i.e. leaves/balls forming a carpet of sorts) when doing so with particles is not desirable (e.g. due to undesirable distribution of items leaving random gaps and overlapping in other places).
